var map = new BMap.Map("allmap");
var point = new BMap.Point(108.95,34.27);
map.centerAndZoom(point,12);
var geolocation = new BMap.Geolocation();

testdiv.value=rs.address;
var testdivip = document.getElementById("testdivip");

});
}else {
alert('failed'+this.getStatus());
}
},{enableHighAccuracy: true})

用post傳到php檔案
php引進下面這個h5 頁面

然後不要搞錯經緯度，就可以做到一張圖上顯示自己位置和他人位置
